Cinamomum camphora (L.) Nees et Eberm. (syn. C. camphora (L.) J. Presl.) is known to exist in a number of chemotypic forms, the most common being those whose oils are rich in linalool (ho oil), camphor and 1,8-cineole. As the first two of these oils have achieved economic importance, particularly ho oil, they will be treated separately within this section.
